Usage

using IpMatcher;

Matcher matcher = new Matcher();
matcher.Add("192.168.1.0", "255.255.255.0");
matcher.Add("192.168.2.0", "255.255.255.0");
matcher.Remove("192.168.2.0");
matcher.Exists("192.168.1.0", "255.255.255.0"); // true
matcher.Match("192.168.1.34"); // true
matcher.Match("10.10.10.10"); // false

Implementation

The matcher uses two primary internal objects. The first is a Dictionary which acts as a faster cache. Success responses to Match will update this Dictionary. On Match requests, the Dictionary is checked first for a match. Behind the Dictionary cache, a list of Address objects are stored.
